AudioQuest's Black Lab cable delivers all the deep bass goodness your powered subwoofer is capable of. This cable features two identical conductors, and each conductor is a single, unbroken strand of AudioQuest's high-purity Long-Grain Copper. Solid conductors eliminate electrical and magnetic interference that can make multi-strand conductor cables sound brittle.

Help your subwoofer sound its best

AudioQuest's Black Lab cable delivers all the deep bass goodness your powered subwoofer is capable of. This cable features two identical conductors, and each conductor is a single, unbroken strand of AudioQuest's high-purity Long-Grain Copper. Solid conductors eliminate electrical and magnetic interference that can make multi-strand conductor cables sound brittle.

High-quality connectors eliminate the weakest link

Black Lab features RCA connectors made of gold-plated copper. The connectors are fastened by cold welding — a solder-less process that uses high pressure and silver paste to minimize signal loss. By contrast, solder tends to impede the signal, and heating the copper conductor can negatively affect its performance.

Flexible, no hum

Works great. It's flexible enough to turn 90 degrees around corners. I went ahead and just connected the ground at both ends of the cable. I haven't tested it without, but I'm receiving good signal and not getting any hum.

Good basic sub cable

Seems to be well built but quite thin in appearance. Using in a small room with sound treatment on two jl audio d110 subs. Not now for the deepest bass but punchy and works excellant in two channel system. Good sub cable for the ptrice.

All you need

This makes my sub sing! Just be sure to point the little arrow on the connector towards the sub for best performance. Build quality and appearance is top notch. A good sub requires a good cable and this is the one to use. No need to spend more.

AudioQuest Black Lab

So far so good the humming stopped coming through my subwoofer. Having that ground wire hook up really helped, thank you great product

AudioQuest Black Lab

Anonymous from Hanover, PA on 11/22/2017

There are more inexpensive or more expensive subwoofer cables practically everywhere, this cable does what is required. Though I am convinced the subwoofer quality is more important than the cable, this Black Lab does not interfere with any musicality. Build materials are more than adequate and frankly it looks good.

AudioQuest Black Lab

Seems to work as it should, but it is on a new sub so I can't compare the sound performance quality to my old cable. My old sub- woofer cable was a lot more solidly constructed - the actual cable was at least twice as thick and the RCA plugs were much more substantial; but it was too short for my new SVS sub. Maybe the "look" of the cable does not affect its performance, but for the price, I guess I expected more. Also, the grounding wires on this AudioQuest cable are a nice feature, but there was no place to ground it to on the sub.

Pros:Works fine, as it should.

Cons:Construction was good, but not as substantial as my old cable that it replaced. Also, no place to ground cable on sub-woofer.

Works Perfectly

I've spent a decent amount of cash on my prior AudioQuest and Monster Cable subwoofer cables. Neither was long enough for my new subwoofer placement. 20 meters gives me the slack I need and the thin nature of this cable makes it much more convenient to place vs my prior overly thick cables. But most importantly did it change the sound? Nope. A good cable doesn't detract from the sound. And there is no grounding hum caused by the cable, so I'm happy.

Pros:Does not detract from sound, no grounding issue (helps to have a grounding wire), and is flexible and easy to work with.

Cons:None for me! But I could see: Doesn't have braiding (I didn't want it, but if you did) and is not a thick show off cable. Cons to some.

Audio Quest Black Lab

This is my second AudioQuest subwoofer cable purchase since I now have 2 subwoofers. My old one was a Monster cable which worked fine, but this is a little cheaper and feels like better quality. Also it is non directional, the ground wire is available in case of hum. Not an issue in my case.

It's a cable

What more can you say? But the grounding wire is a nice feature, and it is long enough to reach grounding screws on the receiver and subwoofer, without being so long that it gets in the way of other cables.

Awesome Cables

The old. Onkyo Receiver, Bose 6.1 system that's 10 years old, still sounded good and was working well, buy It was out of date. No bluetooth, wifi, usb, etc... In with the New! Yamaha Aventage RX-A840 purchased from a different online retailer. Everything else is from Crutchfield. Cables are AudioQuest Pearl & Cinnamon HDMI. Speaker cables are AudioQuest Type 4 & Rocket 33 for speakers & Black Lab for Sub. SVS SB-1000 Sub (Scratch & Dent) Focal Chorus 705 Bookshelf Speakers & Focal Chorus 716 Floor Speakers. Center Channel Klipsch RP-440C. And all housed in a Rosewood 7ft x 9ft entertainment center with a 3 yr old LED Samsung 50 in TV.
I probably spent $3K 10 yrs ago and I did not use AudioQuest cables. The old system was nice, but my ears have matured away from Bose since upgrading my car system to Focal, listening to Hi-Res music files with a DAC, and having high end Headphones and Earbuds. I understand there are much nicer systems for a lot more money. But, for the money, I am a very happy customer. I would have loved to use a Focal Center, but I needed a center that could hold my TV, and Klipsch had one.
The sound is amazingly Smooth, balanced, and powerful! Everything blends well despite being a front facing 5.1 system. I get Great separation on movies, music, and TV programs. Yamaha does an excellent job of processing and I don't miss having speakers behind or beside me. Very clean Highs, Mids & Lows singing in perfect harmony...

Does what a 15 dollar cable does

My Crutchfield advisor added this cable to my order when we specced out a system. I needed an LFE cable, but this much for this thing??? I was surprised when I saw the price in the order confirmation. I'm alright with buying heavier gauge copper wires for high end speakers and whatnot, to an extent. I have 20 year old monster cable that still works great. But here I think you get about 20 dollars worth of actual value and 30 dollars hype out of these. It's an LFE cable, how fancy must it be?

AudioQuest Black Lab

Cons:Wish it were less expensive...but worth it for the great sound quality

Go Bye-Bye Hum

BUBS from Charlottesville, VA on 6/23/2014

A few months ago I purchased a powered sub-woofer (from Crutchfield). After hooking up to an old sub-woofer cable which ran ~ 35 feet under my living room, I noticed a hum in certain locations of the room. With the advice of my Crutchfield salesperson, I began adjusting the amount of gain and low pass frequency on the new sub-woofer. This seemed to work on and off for a few days. However, since this humming annoyance continued to repeat itself, my salesperson had me examine the old cable and I noticed the end from the receiver differed from the end going to the sub-woofer. This wiring had been installed by someone else and there was a short extension cable at both ends of the sub-woofer cable to meet the distance required! So my salesperson had just the answer with this 39.4 foot Audio Quest Black Lab cable. Since then I have thoroughly enjoyed great bass and freedom from hum! ZILCH! I also think the price for this lengthy cable was very reasonable and I might add even better with some reward points!

Pros:Not bulky or "stiff" so easy to thread through a small hole to run beneath a floor and be out of view.
Allows for a clean and "healthy" bass sound with no hum or interference.

Foamed-Polyethylene Insulation: Black Lab uses air-filled
Foamed-Polyethylene Insulation on both conductors because air absorbs next to no
energy and Polyethylene is low-loss and has a benign distortion profile. Thanks
to all the air in Foamed-PE, it causes much less of the out-of-focus effect
common to other materials.

Metal-Layer Noise-Dissipation System (NDS): AudioQuest's
Noise-Dissipation System prevents a significant amount of RFI from reaching the
equipment's ground plane.

Symmetrical Coax Geometry: Identical positive (+) and
negative (-) conductors prevent the shield being used as an inferior audio
conductor.

Cold-Welded Gold-Plated Plugs: This plug design allows for a
connection without the use of solder, which is a common source of distortion.
Because the ground shells are stamped instead of machined, the metal can be
chosen for low distortion instead of machinability.

Grounding: If you hear noticeable hum in your system after connecting
your subwoofer, please attach the subwoofer cable's ground leads to your audio
gear. Some audio equipment have a ground (GND) connection on the back-panel, if
not, attach the ground spade lugs to any screw on the equipment chassis of both
the source and the subwoofer. Usually, this wire will not need to be connected.

[ MIKE Nov 23, 2016 ]

Good price, right length for where I am placing the subs
[ Kyle Sep 26, 2016 ]

Good quality cable with a built in ground. I have had feedback issues in the past with other subwoofer cables and rca cables that could have been prevented with this simple ground wire.

To get the best possible audio performance from the subwoofer. No other reason is necessary.

3 questions already asked

Yes you can run this in your wall .I have mine running under the sub floor and carpet no problems.The sound quality from the Infiniti sub is excellent
[ MICHAEL Jul 02, 2015 ]

The cable is perfectly acceptable, but the problem will be snaking the thick cable through the walls. So unless you are addressing new construction or a substantive remodeling job, you might want to consider cable raceways or channels.
[ GARRETT Jul 01, 2015 ]

Hi Aaron, Yes it is. Unfortunately I had mine go bad but they come with a five year warranty. So I sent it back to audio quest and they sent me another. I have two but of course the one that went bad was the one in the wall. I hope this helps. Don.
[ DONALD Jun 30, 2015 ]

Yes it is. I pre-wired my house with two of these for my theater. Just remember not to run the wire parallel with the electrical in your home.
[ Christopher Jun 30, 2015 ]

I used it in the wall and it seems to work just fine.
[ Steve Jun 30, 2015 ]

I Put it inside my wall and haven't had any problems with it.
